i allready bought 80 stormshields 3months ago all are 30+block and mix of stats :life,life/str,life/dex,%life,CCreduction,
chance to:...... and also bonus heal from potions
i think bonus heal from potions is underestimated since 12k hp every 30sec in line with 400hp/s but u can burst heal

If you suspect something might go up in price for some reason at some point then the best thing you can do is do the research yourself and not tell anyone. Cause no-one is seriously going to tell you if they found a gold mine and even if they do tell you they found one, be very skeptical about what they say. Why would they crash the market for themselves, out of their good hearts perhaps? While that'd be nice, it's just not happening really.
